IMO that heatsink is way too big,it will most definitely affect the amount of thrust.Even if youre using 3s on that motor you wouldnt REALLY need the heatsink, just very good throttle management.

The jet looks awesome! very nice job

what is the weight of the heatsink? does the motor get hot when at full throttle whithout it? if not, it is not really neccesairy. then you can save the weight and the loss of thrust by not using the heatsink.

looking great jahel !!

Just in case you didnt know
the rounded inlet lip needs to be where the air go's in at the front
and not on the fan itself ,you want a smooth transition all the way
to the fan from the start of the duct .

good luck
